IMPROVEMENT IN UMBRELLA-RUNNERS.

Specification forming part of Letters Patent No. 199,638, dated January29, 1878; application filed July 30, 1877.

To all whom it may concern:

Be it known that I, ADAM GOOD, of the city and county of San Francisco,and State of California, have invented an Improved Umbrella-Runner; andI do hereby declare the following to be a full, clear, and exactdescription thereof, reference being had to the accompanying drawings.

My invention relates to a novel arrangement for securing the braces ofan umbrella in the runner which moves on the handle, so that theycanbereadilydetached therefrom and replaced when necessary.

Referring to the accompanying drawings,

Fi ure l is a side view and Fig. 2 sections of 7 e 7 the runner.

Let A represent the runner-tube, which moves on theinnbrella-handle. Theupper end of this tube I provide with an outward-projecting flange, B,as shown. Gis a short tube, of larger diameter than the tube A, so thatit can slip on over it from the lower end. The upper end of this tube iscrimped, so as to form a semicircular bead, D, inside of which is agroove. The diameter of the upper edge of this bead is large enough toallow it to pass the flange B, while the lower part is small enough tobe stopped by the flange. In this semicircular bead I make as many slotsE as there are braces to be attached. The lower end of each brace isflattened in one direction, and `has a round or other shaped head, F, onits extremity.

When the outside tube C is push ed upward on the runner-tube A, theupper rim of the bead D is carried above the flange B, so as to allowthe heads of the braces to be inserted in the groove, while theflattened shanks enter the slots. When all the braces have been placedin position, I draw the short tube downward until the upper edge of thebead is opposite the edge of the flange B, thus closing the ends of theslots, and preventing the shanks of the braces from coming out. I thensecure the short tube in place by a set-screw or otherwise.

In the present instance I have represented I am aware that it is not newto use the runner with outside tube to form a groove for the insertionof the fastening, as this construction is old; but in all these cases asemicircular u groove was made on both the runner and the outside tube,while I make only a plain iiange on my runner, and pass the semicirculargroove of the outside tube entirely over and around it while placing thefastening in position. This construction materially lessens the cost ofthe article, and greatly facilitates the work.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The runner-tube A, with its iiange B, in combination with the outsidetube C, with its grooved bead D, slots E, and fastening I, substantiallyas and for the purpose described.

In witness whereof I have hereunto set my hand and seal.
